One, technical field:
The present invention relates to a kind of irrigation installation, especially relate to a kind of pressure-adjusting type crop root zone water and fertilizer irrigation controlling system, it is applicable to the irrigation of greenhouse, booth and drilling crop and fruit tree, have water saving, energy-conservation, joint is fertile, the characteristics of taking things easy, can mix fertilising with irrigating, adjustable water saving head keeps stable water pressure simultaneously.
Two, background technology:
Water conservancy is the lifeblood of national economy, is the precious resources of human survival and construction.China is the country that lacks of water resource in the world, and the occupancy volume per person only is equivalent to world occupancy volume per person's 1/4, and the many regional lacks of water in the north are even more serious.Current industrialized agriculture enlarges, but only pays attention to improving microclimate environment, having some defectives aspect the meticulous control technique of pouring water, has restricted energy-conservation, water-saving result.In order to promote industrialized agriculture (greenhouse, booth) to reach a new level, in conjunction with China's actual conditions, enforcement science, meticulous irrigation technique inexpensive, that save water and energy are imperative.
Drip irrigation and infiltration irrigation technology are one of the meticulous irrigation new technologies of saving water and energy, very suitable in the greenhouse, economic crops such as booth or outdoor cropping fruit tree, vegetables, cotton use.China has just introduced complete drip irrigation technique in the eighties, but because of irrigating reasons such as waterpower regulator control system, fertilizer applicator cost of equipment height, promotes very slowly, and the defective of following several respects is arranged in short:
1, adopt with conventional water supply network direct connection supplied with the water source more, and the irrigation system work water pressure easily fluctuates, instability;
Though the system that 2, has is equipped with fertilizer spreading tank or annotates fertile pump special-purpose fertilizing equipments such as " Venturi tubes ", but be difficult for fertilising when hydraulic pressure is low, unstable, operational sequence is many in addition, and the peasant generally is reluctant to use;
3, introduce external proportion expression and inhale fertile device, need pipe network that certain pressure is arranged during work, the expense height about 1500 yuan every, is difficult to promote;
4, design heads such as most of irrigator such as water dropper, drip irrigation pipe, infiltrating irrigation higher (0.06～0.1Mpa), need energy dissipating to drip.On the other hand, reality in conjunction with Chinese countryside, from scientic planting, energy-conservation, water saving economic and practical analysis, general greenhouse, booth area are less, tend to water at random, need with low water head drip irrigation (minute-pressure drip irrigation), with the water fertilising, cost is low, and is easy to operate, be easy to the equipment of the water yield, but meet the equipment appearance as yet at present of above-mentioned requirements.
Three, summary of the invention:
The present invention is in order to solve the weak point in the above-mentioned background technology, a kind of pressure-adjusting type crop root zone water and fertilizer irrigation controlling system is provided, it can adapt to the uniform and stable drip irrigation of low-pressure irrigation system, infiltrating irrigation, the irrigation of nothing pressure, under low water head pressure, supply water at random, without other power pressurization, rational in infrastructure, easy for operation, cheap.
For achieving the above object, the technical solution used in the present invention is:
A kind of pressure-adjusting type crop root zone water and fertilizer control system, it is characterized in that: comprise base, base is provided with elevator, base top is provided with the water pot of regulating and storing, water inlet pipe one end of water pot of regulating and storing is connected with water supply network, the other end is connected with the water level autocontrol valve, and the outlet pipe of the water pot of regulating and storing is exported water pipe with system and linked to each other.
The above-mentioned water pot top of regulating and storing is provided with the fertilizer can that liquid fertilizer is housed, and the drain pipe of fertilizer can links to each other with the outlet pipe of the water pot of regulating and storing.
Be provided with the diving filter in above-mentioned regulate and store water pot and the fertilizer can.
Said system output water pipe is provided with the helix tube that changes fluidised form.
Above-mentioned base is provided with the piston pump that is connected with fertilizer can.
Be equipped with control valve on the water inlet pipe of the above-mentioned water pot of regulating and storing, the drain pipe of fertilizer can and the system's output water pipe.
The above-mentioned water pot of regulating and storing is provided with the water-level observation pipe.
The adjustable range of above-mentioned substructure height is 0～80 centimetre.
Above-mentioned elevator is a hydraulic lifting device.
Above-mentioned elevator is manual step-less adjustment elevator.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
1, the present invention can provide a kind of can be according to crop growth phase water consumption size, utilize hydraulic lift, regulated at will pressure of supply water, and the root district irrigation control system of assurance pressure of supply water voltage stabilizing, adjustable range is between 0～80 centimetre, can adapt to the uniform and stable irrigation of low pressure irrigate band (pipe) and infiltrating irrigation, head supplies water at random under low hydraulic pressure (about 2～4 meters), and water mixes with water simultaneously and executes liquid fertilizer at any time, do not need other power pressurization, energy-saving effect is obvious.Cost of the present invention is low, scientific and reasonable for structure, easy for operation, suitable different scales, greenhouse by solar heat, booth and drilling crop fruit tree dissimilar, different regions are used, can implement liquid manure accurately irrigates, have energy-conservation, water saving, fertile, the effect of taking things easy of joint, can promote to improve the industrialized agriculture yield and quality.
2, the present invention can reduce the energy consumption of existing drip irrigation, infiltrating irrigation system, only needs 2～4 meters heads, is most appropriate to industrialized agriculture and drilling crop and fruit tree and accurately irrigates.
3, the present invention need not any additionaling power and expensive fertilising special equipment, only utilizes the differing heights liquid level to implement the root district and irrigate from pressing principle that liquid manure is mixed the back, and cost is low, and is easy to operate.
4, the present invention can be under the low pressure head automatic water-supply, close automatically, keep the irrigation system stable water pressure, not influenced by the water supply network water pressure fluctuations, make pour water more even.
5, the present invention is rational in infrastructure, compact, complete function, and complete cost is low, and suitable different scales greenhouse, booth and drilling crop and fruit tree are used.
